General Information



Theory of Operation

DIGITAL THERMOSTATIC VALVE (DTV)The digital thermostatic valve (DTV) is controlled by either a master or auxiliary user interface (UI). Power is suppliedto both DTV and UI via a 12 V power supply. The power supply is plugged into a standard 120 V GFCI outlet. Hot andcold water enters the DTV through ¾" NPT inlets. The water is then mixed by a stepper motor that moves a shuttle toincrease or decrease the flow of hot or cold water. The microcontroller, located on the printed circuit board (PCB),controls the stepper motor shuttle. A thermistor monitors the outlet water temperature and provides information to themicrocontroller. The microcontroller then maintains the desired temperature and makes any adjustments neededbased on the thermistor feedback. The water outlets are regulated by six independent solenoid valves which arecontrolled by the UI.

Frame 3-1

MEDIA MODULEThe media module serves as the connection hub between the DTV, UI, Ethernet, steam system, lighted rain panel,speaker tiles, audio line in, incandescent lighting, and line power. The media module communicates directly with acomputer through a wired or wireless Ethernet connection to access music files and internet radio. All devicesconnected to the media module are controlled via the UI(s).

Frame 3-2

USER INTERFACE (UI)The user interface is connected to, and powered by, the media module. A maximum of two interfaces may beconnected to the system, a primary interface - located within the shower, and an optional auxiliary interface - locatedoutside the shower. The UI is designed to be mounted to the finished wall surface. The UI has five icons located onthe face of the unit: POWER, USER 123, USER 456, OK, and Back. In addition to the icons, there is also a dial formenu navigation or the adjustment of temperature, lighting, and volume. The UI communicates through the mediamodule to control all the shower system functions: water temperature, massage, steam, music, as well asincandescent and chroma-lighting.

Frame 3-3

STEAM SYSTEMThe RS485 steam adaptor enables the connection of a Kohler steam generator to your showering system. Atemperature sensor is mounted in the shower allowing the temperature and steam functions to be controlled by theUI.

Frame 3-4

LIGHTED RAIN PANELThe lighted rain panel is powered by the power data system (PDS). The lighted rain panel communicates through thePDS to the media module. Four positionable water tile showerheads and the overhead chroma-lighting are controlledvia the user interface. Chroma-lighting options include solid colors, customizeable color (color dial), and severalpreprogrammed color effects.

Frame 3-5

SPEAKER TILEUp to four speakers may be connected to the media module. Speakers are powered through the media module.Music is accessed through a wired/wireless ethernet connection or via the line in cable. Music functionality includingsound volume is controlled via the user interface.
